Abstract

This paper presents a novel varactor based electronically tunable high impedance surface electromagnetic band-gap (HIS-EBG) metamaterial. The proposed structure is based on two-layer mushroom-like HIS-EBG ground plane, in which by controlling the DC voltages applied to the varactors, the effective capacitance are adjusted and the resonance frequency are tuned. To assess the surface wave suppression property the structure is incorporated, as the ground plane, in a microstrip transmission line and it is experimentally characterized over the 500 MHz ¿ 10 GHz frequency band. Numerical simulations of the dispersion diagram and transmission coefficient for the proposed HIS-EBG structure were performed. Both the simulation and measurement results are compared.
